31bets UK Welcome Bonus
You can claim the 31bets welcome offer across your first three deposits, worth up to £350 in bonus funds and 85 free spins in total.
The 31bets sign up offer is for new customers aged 18 or over in the UK. 31bets needs a UKGC licence to take UK players, so check the licence details in the site footer before you register. Amounts change, so confirm the current figures on the 31bets site before you deposit.
Claim your 31bets welcome bonus in four steps
Register your account
Enter your name, date of birth, and UK address. 31bets runs ID checks under UKGC rules, so keep a passport or driving licence handy. Registration takes about two minutes, and the registration guide covers each field.
Make your first deposit
Pay with a Visa or Mastercard debit card, PayPal, Open Banking, or Pay by Phone, and meet the minimum deposit in the bonus terms. UK law bans credit cards for gambling, so that option does not exist. Some payment methods are excluded from bonus eligibility, so read the terms before you pay. The payments page lists which methods qualify.
Receive the bonus
31bets adds the bonus funds and free spins to your account once your deposit clears.
Play eligible games
Spin eligible slots and watch your wagering progress and the time limit in your account. Bonus funds expire if you leave them untouched past the deadline. The casino hub shows what is available.
Do you need a welcome bonus code?
Look for a promo field on the cashier screen. If the 31bets welcome bonus code is required, enter it before you confirm the deposit. If the screen shows no field, the 31bets welcome code is not needed and the offer attaches to your qualifying deposit. Copy any code exactly as the promotion page prints it, because one wrong character leaves you without the bonus.
Bonus tiers at each deposit stage
The 31bets new customer offer pays 100% on your first deposit, 50% on your second, and 25% on your third. Add the three tiers and the 31bets casino welcome bonus reaches £350 in bonus funds plus 85 free spins. Each tier carries 35x wagering.
| Deposit | Match | Max bonus | Free spins | Wagering |
|---|---|---|---|---|
| 1st deposit | 100% | £200 | 50 | 35x |
| 2nd deposit | 50% | £100 | 25 | 35x |
| 3rd deposit | 25% | £50 | 10 | 35x |
How each game type counts towards wagering
Slots count in full, and everything else counts for less. Take the first tier: a £200 bonus at 35x means £7,000 in bets before you can withdraw. On slots, all £7,000 counts. On blackjack at 10% contribution, the same target takes £70,000 in stakes.
| Game type | Contribution | What it means for you |
|---|---|---|
| Slots | 100% | Every £1 staked counts, so you clear wagering fastest |
| Table games | 10% | £100 staked counts as £10 |
| Live casino | 10% | Open to you, but slow for clearing a bonus |
| Game shows | 5% | £100 staked counts as £5, so treat these as entertainment |
| Sports betting | Excluded | Sports bets fall under separate sportsbook promotions |
